Hello,

I have a PCB with my first LPC project. On PCB I have a LPC1227 and connect over cabel to LPCLINK from LPCxpresso 1114.
I have a connect on a J4 connector, because I don't have small header for a J5.

When a programming in LPCxpresso, Program Flash -> Select file (myproject.axf) and then click OK.

I get a program flash message:

Ni: LPCXpresso Debug Driver v7.8 (May 28 2015 02:56:34 - crt_emu_lpc11_13_nxp.exe build 181)

It is this message OK or not OK, because on my PCB with my schem nothhing.

I have on my LPC 3.3V normal connect all. But for LED blinking not working. I don't know why ?

Yes I double click on left side of number of line and set breakpoints then I get up Error.

But still I don't know where I have a error.

It looks like this is an internal Java error that is reported when running in a Pure IPv6 environment on Windows only.
https://bugs.openjdk.java.net/browse/JDK-8046500?page=com.atlassian.jira.plugin.system.issuetabpanel...

Does this sound like it applies to you?

How are you actually setting the breakpoint? You can just double-click on the margin in the left to set a breakpoint.

I get warnings Breakpoint installation failed: Unknown breakpint type.

I just click on my line number two time for add brekapoint. I have a brekapint type C/C++ type

An then clikc on Debug button (spider)

I get this:

An internal error occurred during: "Launching remote Debug".
IP Helper Library GetIpAddrTable function failed

Give us a clue - what error?

i have a include file IO
This file working without problems for other PIN.
Just for 1.0 no.

If I run debugger and set breakpoint I have a problem with breakpoint .I get error.

If run debugging without brekapoint I have not get error.

I don't know where is the problem.

Then use the debugger to find it...

No working. On pin I have a 1.84 V.

OK sorry, this code is noob code.

Now I will write more transparent:

LPC_IOCON -> R_PIO1_0 = (1 << 1) | (1 << 4) | (1 << 7);

But No working.

For first I would like
set FUNC PIO1.0
then set pull up
and then set digital mode.

LPC_IOCON->R_PIO1_0 = 0x01;

And setting R_PIO1_0 register to 0x01 is doing that :quest:

Did you read the user manual?

Or is this a language or coding problem :quest:

What are you trying to do here :quest:

Read user manual Chapter 6.4.46 R_PIO1_0 register...

Yes, R_PIO1_0 is.

But no working if I set:

LPC_SYSCON->SYSAHBCLKCTRL |= 1 << 16;
LPC_SYSCON->SYSAHBCLKCTRL |= 1 << 31;

LPC_IOCON -> R_PIO1_0 =  0xb8;
LPC_IOCON->R_PIO1_0 = 0x01;

GPIOSetDir(1, 0, OUTPUT);
GPIOSetValue(1, 0, HIGH);

This is my code I get error IOCON has no member, why and how then set.

:~

Because IOCON has no 'PIO1_0' member :O

So look in your IOCON struct and find the correct member (name)...

I would like set PIN 1.0 but I cannot.

This is my code I get error IOCON has no member, why and how then set.

[u]LPC_IOCON -> PIO1_0 = (1 << 7);[/u]
GPIOSetDir(1, 0, OUTPUT);

Hello,
here is my solution:

Where I have a Led, pin 1.0, is reserved and with this program not working.

I change the program for 0.16 pin and then working all, here I have connect second LED.

I have a questions; how correct configure pin 1.0, 0.31 and 0.30 reserved pin? For input pin?

If I click on debug, debugging normal without Error and Warning.

I can press on Play button, but notthing.

Here is my code:

#ifdef __USE_CMSIS
#include "LPC122x.h"
#endif

#include <cr_section_macros.h>
#include <NXP/crp.h>

// Variable to store CRP value in. Will be placed automatically
// by the linker when "Enable Code Read Protect" selected.
// See crp.h header for more information
//__CRP const unsigned int CRP_WORD = CRP_NO_CRP ;

volatile uint32_t msTicks=0;

// ****************
//  SysTick_Handler
void SysTick_Handler(void)
{
msTicks++;
}

int main(void)
{
/* Enable all three GPIO blocks and IOCON */
LPC_SYSCON->SYSAHBCLKCTRL |= 0xE001001FUL;
LPC_GPIO1->DIR = 1 << 0;
LPC_GPIO1->SET = 1 << 0;

/* Generate 1ms Ticks */
SysTick_Config(SystemCoreClock / 1000);

while (1)
{
switch (msTicks)
{
case 500:
msTicks = 0;
LPC_GPIO1->CLR = 1 << 0;
break;
case 100:
case 200:
case 300:
LPC_GPIO1->NOT = 1 << 0;
break;
}
__WFI();
}
}

I don't have a quartz on pcb, and I setting in system_LPC122x.c
SYSPLLCLKSEL and MAINCLKSEL

#define MAINCLKSEL_Val        0x00000000
#define SYSPLLCLKSEL_Val      0x00000000

for Internal oscilator

my LED connect on P1.0 pin with resistor before --- anode ---- cathode ---- gnd

if I measure voltage on my LED I have a 1.88V.

On CLKOUT pin I don't have nothing just 3,04 V.Measure with Osciloscope

Supply voltage is 3,12V is OK?
